Title: Automatic frequency control system
Inventor: KAWAHARA NOBUAKI
IPC: H04B1/26
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To actualize an automatic frequency control system capable of compensating for a frequency error of tens to hundreds of Hz which is possibly caused in the HF band, etc., when aircrafts pass by each other. SOLUTION: A frequency error detection parts 20 has 1st and 2nd frequency error estimation blocks and the 1st block detects the maximum value of complex cross-correlation between a unique word in a received signal and stored unique words and estimates the frequency error of the received signal from the current frequency offset. When this value is larger than a threshold, it is outputted as a frequency error and when not, the operation of the 2nd block starts. Then complex correlation operation between the unique word of the received signal and a unique word given positive and negative frequency offsets intentionally on a reception side is performed to estimate a frequency error. A final frequency error is estimated through an equivalent process for the error and tan-1 operation. With those errors, the sine wave of a quadrature detector is controlled to correct the frequency error.

Title: Dynamic vector detecting device
Inventor: TANOI HISAYUKI
IPC: H04N19/51
Filed: 1989-05-10
Abstract: PURPOSE:To detect an accurate dynamic vector without increasing the scale of hardware by performing the dynamic vector detection by block matching by using some picture elements in an MC block for an image signal generated by suppressing the space high-frequency component of a moving picture signal. CONSTITUTION:An input image signal (a) has its space high-frequency component out by a low-pass filter circuit 4. Then the output signal (b) of the low-pass filter circuit 4 is used to detect the dynamic vector. Namely, a dynamic vector detecting circuit 5 performs the dynamic vector detection by the block matching by using some picture elements in the MC block for the image signal obtained by suppressing the space high-frequency component of the motion image signal. Consequently, the MC block can be made large without increasing the hardware scale and the accurate dynamic vector can be detected.

Title: Coil driving circuit
Inventor: KANOU KENJI
IPC: H03K17/64
Filed: 1982-06-30
Abstract: PURPOSE:To facilitate the size reduction of an integrated structure, by using a transistor (TR) instead of using a diode for surge absorption. CONSTITUTION:When the base-emitter voltage of the 1st TR1 is VBE1 and that of the 2nd TR21 is VBE2, the collector voltage of the 1st TR1 is limited to VCC+VBE1+VBE2 (VCC: power supply voltage). The impedance of a signal source connected to the input of the TR1 is sufficiently high while an input signal is in a low level state, the current flowing through the TR1 is nearly VCC/R(R: resistance of coil 2) and the current flowing through the TR21 is VCC/hFE.R, where hFE is the common emitter current amplification factor of the TR1. Consequently, the current flowing through a TR21 is reduced to extremely small, so an element of minimum size is usable for integration.
